sub 'if' hasn't been declared

$spit eval 'if Foo { }'
ERROR while compiling eval: Sub 'if' hasn't been declared.
eval:0
➧if Foo { }

(Foo is a non existant symbol). When doing this in rakudo you get:

$ perl6 -e 'if Foo { }'
===SORRY!===
Function 'Foo' needs parens to avoid gobbling block (or perhaps it's a class that's not declared or available in this scope?)
at -e:1
------> if Foo { }⏏<EOL>
Missing block (apparently claimed by 'Foo')
at -e:1
------> if Foo { }⏏<EOL>

maybe you need parenthesis
try

if (Foo) {}

No doubt. But this ticket is about the bad error message in spit 😛
